Hi rk082085,
Got this issue because the operator version not match the server side livesupport files version.
The simply way is update the server side files and the operator both.
Server side package downloads http://cutesoft.net/downloads/folders/21856/download.aspx
new operator downloads http://cutesoft.net/downloads/folders/21869/download.aspx
If you want to use the old server side files with the new operator. please follow the steps below
1. Open file "LiveSupport.exe.config" which under the root of your operator install folder.
2. Add the code below into the <appSettings> section of the file above
<add key="UseOldEncode" value="True" />
Regards,
Ken
